Typbar Injection vaccine

The mechanism of action of the typhoid polysaccharide vaccine involves stimulating the immune system to produce antibodies specific to the polysaccharide antigen found on the surface of the Salmonella typhi bacteria. This vaccine contains purified polysaccharide extracted from the S. typhi bacterium, which is the causative agent of typhoid fever. When the vaccine is administered, the immune system recognizes the foreign polysaccharide as an antigen, triggering a response. B cells, a type of white blood cell, become activated and start producing antibodies tailored to bind to the specific polysaccharide structure. These antibodies then circulate in the body, and if a person is later exposed to S. typhi bacteria, the antibodies can quickly identify and neutralize the bacteria, preventing or reducing the severity of typhoid fever.

Injection

The following are the uses of typhoid polysaccharide vaccine injection:

• Used for preventing typhoid fever in individuals over 2 years of age, particularly travelers to high-risk areas.
• Used for immunization campaigns to control typhoid outbreaks and reduce disease burden in endemic regions.
• Used for vaccinating individuals at high risk of exposure, such as healthcare workers and food handlers.
• Used for pre-exposure prophylaxis for those living or working in typhoid-endemic areas.
• Used for travelers to regions with poor sanitation and limited access to clean water.
• Used for individuals with close contact with typhoid carriers or infected patients.
• Used for protecting against potentially severe complications of typhoid fever.

In the case of an overdose of the typhoid polysaccharide vaccine, it is important to remain calm and seek medical advice promptly. While rare, an overdose may cause an exaggerated immune response, leading to increased fever, pain, and inflammation at the injection site. Observe the patient for any unusual symptoms, and contact a healthcare professional for guidance. They will provide specific instructions based on the individual's condition and the severity of the overdose.

In the case of a missed dose of typhoid polysaccharide vaccine, it is important to consult your healthcare provider as soon as possible. They will guide you on the appropriate action to take, which may involve scheduling a new appointment for the missed dose. Depending on the timing of the missed dose, your healthcare provider may recommend administering the vaccine as soon as possible or waiting for a specific interval before giving the next dose to ensure optimal protection against typhoid fever.

To administer the typhoid polysaccharide vaccine, clean the injection site with an alcohol swab, insert the needle at a 90-degree angle into the muscle, inject the vaccine, and then withdraw the needle while applying pressure with a sterile gauze pad to prevent bleeding.

Following are the conditions or situations when the Typhoid Polysaccharide Vaccine should not be administered:

• Allergy • Not to be used if the individual has a known or suspected severe allergic reaction to the vaccine or any of its components.
• Age • Not recommended for infants and children below 2 years of age.
• Immune suppression • Should be avoided in individuals with a weakened immune system, such as those with HIV/AIDS, cancer, or receiving immunosuppressive therapy.
• Recent vaccination • If other live vaccines have been administered recently, the Typhoid Polysaccharide Vaccine should be postponed.
• Fever or infection • The vaccine should not be given to individuals with a severe fever or acute illness. It is best to wait until the condition improves.
• Pregnancy • Although there is limited data on the use of this vaccine during pregnancy, it is generally recommended to avoid live vaccines during pregnancy, so it is usually not given to pregnant women.
• Breastfeeding • It is generally advised to consult a healthcare professional before taking any medication or vaccine while breastfeeding.
• Guillain-Barré Syndrome • Not recommended for individuals with a history of Guillain-Barré Syndrome (GBS) after receiving a typhoid vaccine.
• Previous reaction • If an individual has experienced a serious adverse event after a previous dose of the vaccine, subsequent doses should not be given.

The side effects of typhoid polysaccharide vaccine injection may include:

• Fever
• Headache
• Pain and swelling at the injection site
• Nausea and vomiting
• Skin rash or itching
• Diarrhea
• Fatigue and weakness
• Joint and muscle pain

Following are the precautions and warnings for typhoid polysaccharide vaccine injection:

• This vaccine is not recommended for individuals with a history of severe allergic reactions to its components or previous doses of typhoid vaccines.
• Patients with a weakened immune system due to HIV/AIDS, cancer, or other medical conditions should use with caution, as the vaccine's effectiveness may be reduced.
• Ensure that the healthcare provider is aware of any ongoing or recent illnesses, as vaccination might need to be postponed until full recovery.
• Inform your doctor if you have a bleeding disorder or are on blood-thinning medications, as this may affect the administration method.
• As with any vaccine, there is a small risk of allergic reaction. Seek immediate medical attention if you notice signs of a severe allergic reaction like difficulty breathing, hives, or swelling.
• Mild fever, headache, and soreness at the injection site are common side effects, but consult a healthcare professional if these symptoms persist or worsen.
• This vaccine does not provide 100% protection against typhoid fever, and caution should still be exercised when traveling to or residing in areas with a high risk of typhoid.

Following are the drug interactions for Typhoid Polysaccharide Vaccine Injection:

• Typhoid vaccine may reduce the effectiveness of live attenuated vaccines, such as the oral typhoid vaccine or measles-mumps-rubella (MMR) vaccine. Separate administration by at least 3 days.
• Immunosuppressive agents, including corticosteroids and chemotherapy, can decrease the immune response to the vaccine.
• Anticoagulants like heparin or warfarin may increase the risk of bleeding at the injection site.
• Typhoid vaccine can be given with other inactivated vaccines, but different injection sites and separate syringes should be used.
• Concomitant use with other live vaccines may interfere with the immune response to one or both vaccines.
• Anticonvulsant medications may reduce the vaccine's efficacy.
• Certain medications like chloramphenicol and other antibiotics may interfere with the vaccine's effectiveness.

Following are the food interactions with Typhoid Polysaccharide Vaccine Injection:

• Avoid live or live-attenuated vaccines within 30 days before and after vaccination, as the vaccine's effectiveness may be reduced.
• Stay hydrated and maintain a balanced diet to support your immune system's response to the vaccine.
• Avoid excessive alcohol consumption as it may weaken your immune system and reduce the vaccine's effectiveness.
• There is no specific food restriction after the vaccine, but ensure you eat a healthy and nutritious diet.
• No known interactions with specific foods for this vaccine.
• Certain medications, especially immunosuppressants, can affect the vaccine's efficacy, so inform your healthcare provider of any medications you're taking.
• Follow any dietary guidelines provided by your healthcare professional for a smooth vaccination process.

Typhoid Polysaccharide Vaccine Injection should be stored in a cool, controlled environment, preferably between 2°C and 8°C (36°F and 46°F) in a refrigerator. It is crucial to protect the vaccine from light and moisture, so store it in its original packaging until ready for use. Do not freeze the vaccine as it can damage its potency. Once the vaccine is reconstituted, it should be used immediately, and any unused portion should be discarded without reuse. Proper disposal of the vaccine is essential; do not dispose of it in regular household waste or pour it down the drain. Contact your healthcare provider or pharmacist for guidance on safe disposal methods to ensure environmental protection. Keep the vaccine out of the reach of children and pets to prevent accidental exposure.
